A rolling bearing comprises an outer ring, an inner ring and a plurality of rolling elements disposed between the outer and inner rings in such a manner as to freely roll therebetween. At least a member selected from the outer ring, inner ring and rolling elements is such that the content of C is not less than 0.2 wt%, not more than 0.6 wt%, the content of Cr is not less than 2.5 wt%, not more than 7.0 wt%, the content of Mn is not less than 0.5 wt%, not more than 2.0 wt%, the content of Si is not less than 0.1 wt%, not more than 1.5 wt%, the content of Mo is not less than 0.5 wt%, not more than 3.0 wt%, and a carburizing or carbo-nitriding treatment, a quenching treatment and a tempering treatment are applied thereto, and conditions are satisfied in which the volume of retained austenite on a surface thereof is not less than 15%, not more than 45% by volume ratio, and the surface hardness is not less than HRC60.
